. SPECIFICATION forming part of Letters Patent No. 755,858, dated March29, 1904.

Application filed October 2'7, 1908. Serial No. 178,670. (No model.)

To all whom it may concern:

Be it known that I, MICHAEL M. DUNGAN, a citizen of the United States,and a resident of Homer,.in the county of Champaign and State ofIllinois, have made a certain new and useful Invention in Gates; and Ideclare the following to be a full, clear, and exact description of thesame, such as will enable others skilled in the art to which itappertains to make and use the invention, reference being hadto theaccompanying drawings, and to letters and figures of reference markedthereon, which form a part of this specification.

Figure 1 ,is a perspective view of my invention with the gate in closedposition against the latch-post. Fig. 2 is a similar view with the gatein open position against the side post. Fig. 3 is a section on the line3 3, Fig. 1. Fig. 4 is a perspective view of the latch devices indetail. Fig. 5 is a detail view of the latch-bolt device.

The invention relates to swinging farmgates; and it consists in thenovel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the letter adesignates the body of the gate; 1), the hinge-post for the gate; 0, thelatch-post, and d the side or road post. A guide-post e is providedusually between the hinge-post and the road-post for the hingelever f,which is slotted near the hinge-joint for the passage of the guide-post.The hingepost and the road-post are provided with shoulders or fulcrumsat g for the branches of the lever fi.

it represents a triple-arm toggle-jointed connection, the middle arm ofwhich is attached to a slide-rod k, arranged in bearings it along thetop of the gate. This slide-rod is provided with a coil-spring 1, thetension of which is adjusted in bearings to cause the slide-rod to pushforward or toward the looking edge of the gate, and the arm 2 of thetriple-bar connection it is connected to said slide-rod in front of saidspring. This is accomplished by means of a short slide-rod attachmentif, having a lateral lug 75, to which the arm 2 is connected. Thelateral lug k abuts forwardly against one of the slide-bearings l0, andthe coil-spring 1, which surrounds said slide-rod attachment in rear ofsaid lug, abuts in rear against one of said slidebearings k. The arm 3of the triple-bar connection is attached to the road-lever f and the arm4 to a side bar or bearing on between the hinge-post and the road-post.The attachments of the arms of the triple-bar connection are pivotal incharacter. The three arms 2, 3, and 4 of the connection h are pivotedtogether in such wise that they have radial movement from the commonpivotal center.

.Near the swinging end of the gate is provided a double lever latch-boltdevice 10, which consists of the vertical levers 6 and 7 pivotedtogether at their adjacent ends and pivoted to bearings 8 of the gate.The levers 6 and 7 carry the bolts n, which are designed to extendthrough bearings g of the gate. To the upper end of the double lever isconnected the end of the slide-rod 7:, and when the sliderod is pulledtoward the hinge end of the gate the double lever will be operated towithdraw the bolts 12 by endwise movement out of engagement with thelatches of the latch-post.

The latching arrangement is double, there being preferably two latcheson the post 0, one being above the other in corresponding position tothe bolts n of the gate, whereof one is near its upper portion and theother near its lower portion. The latches are indicated at 2 a, and eachconsists of a gravityhook w, normally resting on a guide bearing andstop '0 and forming therewith bolt-receiving recesses. The gravity-hooksof the two latches are connected by a handle-rod q, working in bearingss of the post, as indicated. The two latches may be operated together atthe latchpost by means of this handle-rod, rendering it unnecessary fora foot-passenger to pull the operating-arm of the road-lever.

The gate when closed is supported at one end by its hinges and at theother by the guide-bearings o, on which the bolts of the gate rest.These bolts have longitudinal horizontal movement and brace the gatewhen it is closed in a strong manner. As the gravitylatches will notopen automatically, it is necessary to withdraw the bolts before thegate can be moved by means of the lever devices. The guide-bearings ohave no keeper projections, so that the gate is not jolted in closing.

In opening the gate for a team the roadlever is pulled, therebyextending the arms 3 and 4 of the triple-bar connection and pulling thearm 2, which pulls the slide-rod of the gate, withdrawing the bolts nand continu'ing its action pulls the gate open. The gate swings openuntil it rests against the roadpost, when the arms 3 and 4 will beforced closed toward each other and toward the gatearm 2 in reverseposition from that which they have when the gate is closed. In thisreversed position the gate is held open by the bracing action of the twoarms 3 and 4, so that there is no liability of its swinging closed uponthe team or moving at all until the roadlever is pulled to reverse theaction of the triple-bar connection and close the gate. The engagementof the bolts a, which in closing the gate are protruded with thegravityhooks of the latches, is prompt, there being no liability tospring out of the latches, The lock is secure, and there is no liabilityof the bolts being thrown out by stock. The bearings of the latches areengaged by the bolts n of the gate in such wise as to relieve thehinge-post of strain and put the weight of the gate equally on thehinge-post and the latchpost.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a gate, the combination of the slidebearings, the slide rod havingmovement in such bearings, a slide-rod attachment having a lateralstop-lug abutting at its forward end against one of said slide-bearings,a spring in connection with said slide-rod attachment and in rear ofsaid lug, pivoted bolt-levers connected to said slide-rod,longitudinally-movable latch-bolts, a triple toggle-arm device connectedto the lateral lug of said slide-rod attachment, and a road-leverconnected to said triple-arm device, substantially as specified.

2. In a gate, the combination of the slidebearings, the straightslide-rod having movement in such bearings, and provided with a lateralstop-lug abutting forwardly against one of said slide-bearings, a springfor pressing said slide-rod forwardly and located in rear of said lug,pivoted bolt-levers connected to said slide-rod,longitudinally-movablelatchbolts, a triple toggle-arm device connected to said lateral lug,and a road-lever connected to sfiaili triple-arm device, substantiallyas speci- In testimony whereof I afiiix my signature in presence of twowitnesses.
